    /*
      Reverse-engineer's notes:

      The Hasselblad gain tag (0x19 in makernotes) is only available in the 3FR format and
      is applied and removed when Hasselblad Phocus converts it to the FFF format. It's
      always 0x300000 bytes large regardless of (tested) model, not all space in it is
      used though.

      It contains individual calibration information from the factory to tune the sensor
      performance.

      There is more calibration data in the tag than what is applied in conversion to FFF,
      I've only cared to figure out the data which is actually used, but have some leads on
      remaining info.

      The format is not equal between all models. Due to lack of 3FR files (harder to get
      than FFF) only a subset of the models have been reverse-engineered.

      The header space is 512 bytes and is a mix of 16 and 32 bit values. Offset to blocks
      are 32 bit values, but all information seems to be encoded in 16 bit values. Many
      values in the header can be zeroed with no effect on FFF conversion, and their
      meaning, if any, have not been further investigated.

      Formats:
      hdr16[22] = raw width
      hdr16[23] = raw height
      hdr32[24] = offset to level corr block
         Data block format. Seems to differ depending on sensor type. For tested H4D-50
         and H3D-31: 10 16 bit signed values per row
         value 0: a correction factor (k) used on even columns, where the new pixel value is
         calculated as follows:
         new_value = old_value + (2 * ((k * (old_value_on_row_above-256)) / 32767) - 2)
         note the connection to the value on the row above, seems to be some sort of signal
         leakage correction.
         value 1: same as value 0 but using old value on row below instead of above
         value 2-3: same as value 0-1 but for odd columns
         value 4-9: has some effect if non-zero (probably similar to the others) but not
         investigated which, as it's seems to be always zero for the tested cameras.

      hdr32[25] = probably offset to "bad/unreliable pixels" info, always 512 as it starts
                  directly after the header. Not applied in FFF conversion (at least
                  typically).
                  Data block format guess: raw_height packets of
                    <type?><number of coords><coords...>

      hdr32[27] = offset to unknown data (bad colulmns?), of the form:
                  <packet count><packets><0>
                  packet: <column><?><?><?>.

      hdr32[34] = curves offset, seems to be A/D curves (one per channel) on newer models
                  and some sort of a film curve on older. Not applied in FFF conversion.

      hdr32[36] = flatfield correction, not available in older models. Data format:
                  <1><block width><block height><rows><cols><11 * 2 pad><packets>
                  packet: <R><G1><G2><B>

                  The header pad is not zeroed and might seem to contain some sort of
                  information, but it makes no difference if set to zero. See
                  hasselblad_correct() how the flatfield is applied.

      Applied in FFF conversion is levels, flatfield correction, and the bad columns(?)
      data. A/D curves are surprisingly not applied, maybe pre-applied in hardware and
      only available as information? Levels are applied before flatfield, further
      ordering has not been investigated.

      Not all combinations/models have been tested so there may be gaps.

      Most clipped pixels in a 3FR is at 65535, but there's also some at 65534. Both
      are set to 65535 when calibrated, while 65533 is treated as a normal value. In
      the calibration process smaller values can be scaled to 65534 (which should
      not be seen as clipped).
